AD22305 Gyroscope Data Sheet?

Rate is nearest to the edge of the board, Temp is next to it. Your board may be mislabeled, but I thought those boards had a special notice shipped with them.

All working now, thanks guys.
It was just some poor welding

I'd like to work on temperature compensation to improve results, but I can't find information on temperature effects.

The datasheet has been attached!

The data sheet that Eric just posted has the temperature effects too. The gyro code in the WPI Robotics Library calculates the bias when starting. This means the initial temperature drift is compensated for. Only if you plan to change temperatures without recalibrating the gyro would temperature compensation be needed, in my opinion.
